These servers are currently on the same host, but may not be in the
future. They are in a vm cluster (though honestly, I'm not sure what
this means yet).
SElinux is on, but disabled.
Firewalling through iptables is turned off via system-config-securitylevel
There is no line currently in the cluster.conf that deals with multicasting.
Any other suggestions?
